Mössbauer absorption spectra in amorphous metallic alloys

We have calculated Mössbauer quadrupole and hyperfine spectra of ${}_{}{}^{57}{}_{}{}^{}\mathrm{Fe}$ using a computer-generated dense random structure to model the atomic arrangements. The close qualitative agreement with experiments on alloys of iron with either metalloid (P, C, and Si) or rare-earth metals provides additional support for this model as a description of the short-range order in these materials.
